Discussion
- The tL-dataset of GeraPoul2005 has been split up, because we think the "adults" are food limited. This is indicated by slower growth after reaching 0.3320 cm. Therefore during parametrisation the "adults" (tL3) got a lower f than the younger snails (tL2)
- Gaia2016 are measurements from cohort cultures, age classes 0-14 days, 14-47 days, 47-75 days, 75-119 days, 119-173 days, 173-223 days, 223-251 days and 251-323 days
Facts
- \emph{Potamopyrgus antipodarum} is ovoviviparous and parthenogenic. (Ref: Wiki)
